Model 102 Data Sheet High Quality Groundwater and Surface Water Monitoring Instrumentation ® Solinst is a registered trademark of Solinst Canada Ltd. Coaxial Cable Water Level Meter Laser Marked Water Level Meter Model 102 The Solinst Model 102 Water Level Meter is designed to measure groundwater levels, especially in small diameter tubes and piezometers, or where a flexible assembly is needed to get past down hole instrumentation. Also available from Solinst, are the Model 101 and 101B Water Level Meters, which feature easy-to-read, easily repaired flat tape. (See Model 101 Water Level Meter Data Sheets). Operating Principles The Model 102 Water Level Meter uses a choice of two small diameter probe designs, attached to a narrow coaxial cable, fitted on a sturdy ergonomically designed reel. A standard 9 volt battery, housed in an easy-access battery drawer, powers the Water Level Meter. When the probe enters water the electrical circuit is completed, sending a signal back to the reel where a light and clearly audible buzzer are activated. The water level is then determined by taking a reading directly from the cable at the top of the well casing or borehole. A sensitivity control allows the buzzer to be scaled back or turned off while in cascading water, and ensures a clear signal in both high and low conductivity conditions. Probes Model 102 Probes are designed for flexibility. The probe tips use a recessed design to minimize false signals in cascading water. P4: 0.157" dia. x 1.5" long (4 mm x 38 mm) stainless steel weighing 0.35 oz (10 g). It is ideal for accessing narrow diameters, especially the channels of a Solinst CMT System. P10: 3/8" dia. x 2.75" long (10 mm x 70 mm) stainless steel with 10 stainless steel weights, weighing 6.14 oz (174 g). This heavier probe assembly is ideal for greater depths. • Solinst quality at a low price • 0.157" (4 mm) diameter probe • Rugged, corrosion resistant components • Strong, flexible cable is easily spliced • Replacement probes, cables and parts • Precise markings every 1/100 ft. or mm • Traceable to national standards Low Cost Narrow Long Life Accurate Features Laser Marked Cable The coaxial cable has a durable polyethylene jacket with permanent markings precisely laser etched on the cable every 1/100 ft. or each millimeter. The cable reels smoothly, remains flexible, and comes in lengths from 100 ft. - 1000 ft. (30 m - 300 m). A braided copper outer conductor gives flexibility and a stranded stainless steel central conductor gives strength. It is easy to repair and splice.
